The Test System and Thermal Results
Testing for the CPU coolers is done with the use of RealTemp to ascertain temperatures, Intel Burn Test to deliver the load to the CPU and CPU-Z to verify the CPU speed and the voltage being used in Windows. All of the testing is done with an ambient temperature of 24.5-25°C and humidity is maintained to 35% sometimes less.
For the "stock" runs, it's more of a plug and play setup where the PWM of the motherboard is in control of the fans speeds for both the idle and load results. Speed Step is active and the processor idles at 1600 MHz and loads at 3500 MHz for the stock settings. I also set the memory to run at 1600 MHz for stock. As for the overclocked runs, I load the CPU at 4.5 GHz and idle results are obtained with 7.5V to the fans while the load run is set to deliver 12V to the fans. This allows me to gauge the lowest and highest fan ratings for my charts.
You will also see that the charts have been slightly adjusted. From now on I will mention the idle temperatures if there is something worth noting other than an average of twenty-five to twenty-seven degrees as the PWM controls and Speed Step allow for almost ambient results in most instances. What you are now getting is a stock speed loaded temperature chart and an overclocked loaded temperature chart. To clean up the audio results, I also removed all of the fans that aren't on the thermal charts. If you want to compare those results to new coolers, the old chart is still available in the older reviews.
The TD03 falls just behind the Kraken X40 and the Water2.0 Pro by one degree, and is only out of first place by four degrees for the stock level of testing. This is in my opinion a very good, if not slightly expected result at this level.
With the overclock applied and the fans running full speed, as the pump was already running full speed in both tests, the efficiency stays very close to the other AIOs I mentioned. Just at this level the H60 (2013) also pops in slightly ahead of the TD03, but it is still within four degrees of the best AIO on the market currently. With all the new design elements in play here, I think the TD03 does well in the thermal testing, and I can find no reason to discounts its cooling capabilities.
